Antioxidant and antibacterial properties of lemon, sweet, and cereal grasses

Abstract

There is currently growing interest in using plants as a source of bioactive compounds that exhibit beneficial health properties. Moreover, consumers are becoming increasingly more concerned about the quality of food, thus, newly introduced products and additives should be nutritious, healthy, safe, and friendly to both the environment and animals. Much attention is currently being paid to plant-based diets that prioritize the consumption of fruits, vegetables, nuts, seeds, grains, and botanicals, and a focus on plant content reinforces observed growing interest in vegetarian and vegan products and a flexitarian lifestyle (Mintel Report, 2017). It should also be emphasized that plant extracts containing various antioxidant and antimicrobial compounds are becoming more interesting because they can be used to either prevent or retard undesirable changes, for

Evaluation of the Efficacy of Antioxidant Extract from Lemon By-Products on Preservation of Quality Attributes of Minimally Processed Radish (Raphanus sativus L.)

“…Among the various bioactive compounds found in LP E , eriocitrin and hesperidin were identified as the most plentiful flavonoids with a content of 33.4 ± 0.14 and 47.2 ± 0.19, respectively, followed by gallic acid, narirutin, p-cumaric acid, neoeriocitrin, naringin, rutin and ferulic acid. These compounds are known for their significant antioxidant and antimicrobial activity, with well-known beneficial effects on human health [30,43].…”

“…The presence of LP E in the alginate-based coating formulation (CRd) did not express a great variation in this qualitative parameter, as instead demonstrated by Rojas-Graü et al [45] and Raybaudi-Massilia et al [48] regarding the active coating applied to cut apples. The lack of an antimicrobial effect by LP E in the dipping and coating formulations could be due to the antioxidant extract's pool of secondary metabolites, such as tannins, flavonoids and phenolic compounds, which are known to have antimicrobial properties [43]. Indeed, as stated by Ivasenko et al [49], the extraction method of valuable compounds from plant matrices is crucial to the composition of the final extract.…”
